1 1/2 cups good semi sweet or dark chocolate chips
1/2 c. cream
1 tsp vanilla or 1/4 tsp mint extract
Place chocolate in a medium bowl. Heat cream just till boiling (watch carefully). Pour over chocolate and let sit 5 minutes. Whisk until smooth, adding extract. Cool in fridge 2 hours. Shape into teaspoon sized balls. Refrigerate over night and roll in desired coating: cocoa, powdered sugar, fine nuts, chocolate coating, sprinkles etc.
Note: I mixed powdered sugar and cocoa together for the coating so it's not so bitter.
